Current trend in the treatment of patients with nephrolithiasis is decreasing of the invasiveness of the surgery. Recent technical innovations for effective stone disintegration, permanent kidney access, good visualization of endoscopy and decrease in the instruments size raised the urological interest in efficacy and improvements in the area of retrograde intrarenal surgery (RIRS) for large and staghorn urinary stones. It is typical for RIRS to have high efficacy (50-94.6%) and low rate of perioperative complications.

The social significance of urolithiasis in recent years, finds a new urgency to the global changes in the health of the world population. Tendency of progressive increase in the prevalence of the urolithiasis is obvious, which requires the development of highly efficient methods of prevention and minimally invasive methods of treatment. In recent years there has been a multi-disciplinary approach to the study of the urolithiasis due to principles of evidence based medicine.

The purpose of the study – a synthesis and analysis of experience with transurethral endoscopic techniques in patients with large renal stones and staghorn nephrolithiasis.
